Dragon Quest IX

It heals the user for around 80 health and can be used inside a battle as well as outside a battle. It costs 4 MP to use.

It can be learned by some bosses as well: Corvus, Tyrannosaurus Wrecks, and Nimzo. The bosses' versions of this skill heals for 500 health instead of the normal 80 health.

Though it can only heal the user it is still very useful as it is one of the few healing techniques that can be used in different vocations (once it is acquired) and can serve as an auxiliary healing technique (it also restores a decent amount of HP).
